North Korean hackers have conducted a global cyber espionage campaign in efforts to steal classified military secrets to support Pyongyang's banned nuclear weapons programme, the United States, Britain and South Korea said in a joint advisory on Thursday.
The hackers, dubbed Anadriel or APT45 by cybersecurity researchers, are believed to be part of North Korea's intelligence agency known as the Reconnaissance General Bureau, an entity sanctioned by the U.S. in 2015.
In April 2024, FrostyGoop, an ICS malware, was discovered in a publicly available malware scanning repository. FrostyGoop can target devices communicating over Modbus TCP to manipulate control, modify parameters, and send unauthorized command messages. Modbus is a commonly used protocol across all industrial sectors. The Cyber Security Situation Center (CSSC), a part of the Security

Sekoia.io investigated the mysterious 7777 botnet (aka. Quad7 botnet), published by the independent researcher Gi7w0rm inside the “The curious case of the 7777 botnet” blogpost.
This investigation allowed us to intercept network communications and malware deployed on a TP-Link router compromised by the Quad7 botnet in France.
To our understanding, the Quad7 botnet operators leverage compromised TP-Link routers to relay password spraying attacks against Microsoft 365 accounts without any specific targeting.
Therefore, we link the Quad7 botnet activity to possible long term business email compromise (BEC) cybercriminal activity rather than an APT threat actor.
However, certain mysteries remain regarding the exploits used to compromise the routers, the geographical distribution of the botnet and the attribution of this activity cluster to a specific threat actor.
The insecure architecture of this botnet led us to think that it can be hijacked by other threat actors to install their own implants on the compromised TP-Link routers by using the Quad7 botnet accesses.
A Telegram for Android zero-day vulnerability dubbed 'EvilVideo' allowed attackers to send malicious Android APK payloads disguised as video files.
Spanish police arrested three suspected members of the pro-Russian hacker group NoName057(16), known for carrying out distributed denial-of-service (DDoS) attacks against Ukraine’s allies.

On May 2, 2024, Arctic Wolf Labs began monitoring deployment of a new ransomware variant referred to as Fog. The ransomware activity was observed in several Arctic Wolf Incident Response cases, each exhibiting similar elements. All victim organizations were located in the United States, 80% of which were in the education sector and 20% in the recreation sector.
We are sharing details of this emerging variant to help organizations defend against this threat. Please note that we may add further detail to this article as we uncover additional information in our ongoing investigation.

You can hide data in directory structures, and it will be more or less invisible without knowing how to decode it. It won't even show up as taking up space on disk. However, its real-world applications may be limited because it is the code execution itself which is often the difficulty with AV/EDR evasion.
Spanish Police arrested three individuals on July 20, 2024, who are suspected of participating in a series of cyberattacks targeting critical infrastructure and government institutions in Spain and other NATO countries.
The detainees are believed to be affiliated with the hacktivist group NoName057(16), known for its pro-Russian ideology and launching DDoS attacks against entities supporting Ukraine in the ongoing conflict.
On July 19, 2024 at 04:09 UTC, as part of ongoing operations, CrowdStrike released a sensor configuration update to Windows systems. Sensor configuration updates are an ongoing part of the protection mechanisms of the Falcon platform. This configuration update triggered a logic error resulting in a system crash and blue screen (BSOD) on impacted systems.
The sensor configuration update that caused the system crash was remediated on Friday, July 19, 2024 05:27 UTC.
This issue is not the result of or related to a cyberattack.
On July 18, CrowdStrike, an independent cybersecurity company, released a software update that began impacting IT systems globally. Although this was not a Microsoft incident, given it impacts our ecosystem, we want to provide an update on the steps we’ve taken with CrowdStrike and others to remediate and support our customers.
